[tex]Day\ 2 = 16550[/tex]
what the midpoint between the point 2,6 and "-4,6
Answer: (-1, 6)
Step-by-step explanation:
Use the midpoint formula:
(Xm, Ym) = ([x1 + x2]/2, [y2 + y1]/2)
(Xm, Ym) = ([2 + -4]/2, [6 + 6]/2)
(Xm, Ym) = (-2/2, 12/2)
(Xm, Ym) = (-1, 6)
The midpoint is (-1, 6)
Which products result in a difference of squares? check all that apply. (5z 3)(–5z – 3) (w – 2.5)(w 2.5) (8g 1)(8g 1) (–4v – 9)(–4v 9) (6y 7)(7y – 6) (p – 5)(p – 5)
Option second [tex]\rm (w-2.5)(w+2.5)[/tex] and option fourth [tex]\rm (-4v-9)(-4v+9)[/tex] are the products that result in a difference in squares
It is required to identify which products result in a difference of squares.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We know that:
[tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]
In option first:
[tex]\\\rm= (5z+3)(-5z-3)\\\rm =-(5z+3)(5z+3)\\\rm =-(5z+3)^2[/tex]
It is not the difference between squares.
In option second:
[tex]\rm = (w-2.5)(w+2.5)\\\rm = (w^2-2.5^2)[/tex] By using [tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]
It is the difference between squares.
Similarly, in option third:
[tex]\rm = (8g+1)(8g+1)\\\rm = (8g+1)^2[/tex]
It is not the difference between squares.
Similarly, in option forth:
[tex]\rm = (-4v-9)(-4v+9)\\\rm = (4v+9)(4v-9)\\\rm = (4v)^2-9^2[/tex]
It is the difference between squares.
Similarly, in option fifth:
[tex]\rm = (6y+7)(7y-6)\\\rm = 42y^2+13y-42[/tex]
It is not the difference between squares.
Similarly, in option sixth:
[tex]\rm = (p-5)(p-5)\\\rm = (p-5)^2[/tex]
It is also not the difference between squares.
Thus, option 2 and option 4 are correct.

What value belongs next to the 1 in the table? What does it mean in this context?
Answer:
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)
Step-by-step explanation:
The value next to 1 in the table above = number of dimes we have in 1 quarter.
Let the value next to 1 be "x".
That is:
1 quarter = x dimes
If 4 quarters = 10 dimes, then,
Cross multiply to find, how many dimes, x is equal to.
Thus:
1*10 = 4*x (cross multiplication)
10/4 = 4x/4 (dividing both sides by 4)
2.5 = x
The number next to 1 is 2.5.
It means 2.5 dimes are in 1 quarter (1 quarter = 2.5 dimes)
Carpet Plus installs carpet for $100 plus $8 per square yard of carpet. Carpet World charges $75 for installation and $10 per square yard of carpet. Find the number of square yards of carpet for which the cost including carpet and installation is the same.
Answer:
12.5 square yards.
Step-by-step explanation:
Let a square yard of carpet = x
The cost of installing a carpet is given by;
100 + 8x
The charge for installation
75 + 10x
The number of square yards of carpet for which the cost including carpet and installation is the same is given by;
100 + 8x = 75 + 10x
100 - 75 = 10x - 8x
25 = 2x
x = 25 / 2
x = 12.5 square yards.

C) The population included builders who build homes in any town.
D) The population included builders who do not build homes in Vicki’s town.
E) The builders were referred to Vicki by the realtor who will be selling the houses.
Answer:
Options A & B are correct.
A) The builders were chosen at random.
B) The population included only builders who build in Vicki’s town.
Step-by-step explanation:
Looking at the question, we see that Vickie wanted to determine the cost of building a new home in the town in which she lived. Now, she sampled builders who are building in the town in which she lives and thus, it makes the sample more representative.
However, the random method of choosing the builders would help to remove any lingering biases that may arise.
Thus, we can conclude that the builders were chosen at random and that it included only those who build in her town.
Thus, options A & B are correct.
Answer:
A)The builders were chosen at random., B)The population included only builders who build in Vicki’s town.

difference between mass and weight
Mass is how much "matter" something is. Weight is this with respect to gravity. Therefore, if you took a ball to the moon, its mass would not change because the amount of matter is unaffected but the weight will change because the Earth and the Moon have different gravitational pulls.

P(x)=2x+1200
P(x)=8x−1200
P(x)=8x+1200
Answer:
The answer is P(x)8x-1200
Step-by-step explanation:
The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.
What is a profit?A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.
The profit is given as,
Profit = Revenue function - Cost function
Andrew has determined that the revenue and cost functions for a new product line at his business are given by these functions.
R(x) = 5x
C(x) = 1200 + 3x
Then the profit function for Andrew’s new product line will be
P(x) = R(x) - C(x)
P(x) = 5x - 1200 - 3x
P(x) = 2x - 1200
The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.

Find the equivalent rate:
300 miles in 20 seconds to miles per minute.
30 miles per min
15 miles per min
3 miles per min
Step-by-step explanation:
300/20 × 3/3 = 900/60
* 60 sec is 1 min therefore you want to get 60 secs in the denominator. In order to get that, you need to multiply.
900/60 divided by 60/60 is 15/1.
So 300m/20sec = 900m/60sec = 900mpm
If we're to do the same for all then it would be:
30m/20sec = 90m/60sec = 90mpm
15m/20sec = 45m/60sec = 45mpm
3m/20sec = 9m/60sec = 9mpm
Alice was having a conversation with her friend Trina, who had a discovery to share:
Pick any two integers. Look at the sum of their squares, the difference of their squares,
and twice the product of the two integers you chose. Those three numbers are the
sides of a right triangle.
a. Write an equation that models this conjecture using the variables x and y.
b. Investigate this conjecture for at least three pairs of integers. Does her trick
appear to work in all cases, or only in some cases? Explain.
c. Use Trina’s trick to find an example of a right triangle in which all of the sides
have integer length, all three sides are longer than 100 units, and the three side
lengths do not have common factors.
BONUS: If Trina’s conjecture is true, use the equation found in part a to prove the
conjecture. If it is not true, modify it so it is a true statement, and prove the new
statement
Answer:
a. (x² + y²)² = (x² - y²)² + (2xy)²
b. The conjecture works in all cases.
c. Sides of 119, 120, and 169
Step-by-step explanation:
a. Equation that models this conjecture
x² + y² = sum of squares
x² - y² = difference of square
2xy = twice the product of the integers
If these are the sides of a right triangle then
(x² + y²)² = (x² - y²)² + (2xy)²
b. Test the conjecture
(i) Try x = 2, y = 1
(2² + 1²)² = (2² - 1²)² + (2×2×1)²
5² = 3² + 4²
25 = 9 + 16
(ii) Try x = 3, y = 1
(3² + 1²)² = (3² - 1²)² + (2×3×1)²
10² = 8² + 6²
100 = 64 + 36
(iii) Try x = 3, y = 2
(3² + 2²)² = (3² - 2²)² + (2×3×2)²
13² = 5² + 12²
169 = 25 + 144
The conjecture appears to work in all cases.
c. A possible triangle
We must have one side greater than 100. That means,
x² > 100 or x >1 0.
Let x = 12
One side = 12² + y²
The second side = 12² - y²
The third side must have 2xy > 100
24y > 100
y > 4.2
Try y = 5
(12² + 5²)² = (12² - 5²)² + (2 × 12 × 5)²
169² = 119² + 120²
So, one right triangle could have sides of 119, 120, and 169.
Furthermore, these sides have no common factors.
Check:
169² = 119² + 120²
28561 = 14161 + 14400
28561 = 28561
